Population justification: A total of 4,632 individuals were counted in the Asian Waterbird Census in 2004, and 4,428 in 2005 (D. Li in litt. 2005). The total population is likely to fall between 5,000-10,000 individuals, roughly equating to 3,300-6,700 mature individuals.
Trend justification: A steep population decline was evident by the mid-1970s, with high numbers recorded at only a few sites in the following decade. Subsequent local extinctions and near-disappearances have occurred in several significant sites, owing to exceptionally high levels of hunting and trapping, conversion of natural wetlands, mangrove destruction and the recent extensive use of pesticides on rice-fields. This species's population is suspected to be undergoing a rapid and continuing decline in line with these impacts.
